Content transmission device, program, parental level determination method, and content transmission system

A non-transitory computer-readable medium having a computer-readable program stored thereon, the program causing a computer provided in a content transmission device which is connected to a plurality of external devices including a reproduction device reproducing content data and which comprises a transmitting section transmitting content data to the reproduction device to function as:

• a detecting section detecting the state of each of the plurality of external devices;
• a parental level determining section determining for the reproduction device a boundary between a parental level on content data the viewing of which is restricted and a parental level on content data the viewing of which is allowed according to the state of each of the plurality of external devices detected by the detecting section;
• and
• a control section controlling transmission of content data from the transmitting section based on the relation between the boundary determined by the parental level determining section and a parental level set on content data,
• wherein the boundary for the reproduction device is set through a graphical user interface comprising a target device selection display, a target device state selection display, and an age restriction display,
• wherein multiple restriction standards are set for the reproduction device using respective restriction standard setting screens, access to a restriction standard setting screen requiring an authentication process including integrated circuit (IC) card authentication.

A parental level determination method executed by a content transmission device which is connected to a plurality of external devices including a reproduction device reproducing content data, comprising the steps of:

• detecting the state of each of the plurality of external devices;
• determining for the reproduction device a boundary between a parental level on content data the viewing of which is restricted and a parental level on content data the viewing of which is allowed according to the state of each of the plurality of external devices;
• and
• controlling transmission of content data from the transmitting section based on the relation between the determined boundary and a parental level set on content data,
• wherein the boundary for the reproduction device is set through a graphical user interface comprising a target device selection display, a target device state selection display, and an age restriction display,
• wherein multiple restriction standards are set for the reproduction device using respective restriction standard setting screens, access to a restriction standard setting screen requiring an authentication process including integrated circuit (IC) card authentication.
